I ran this yesterday and using the tutorial I could see the vault they suggested loading up and everything. I also updated my video card right after using GECK for this first time. Today, when I opened my saved file, or even the default file, the Render Window is gray. Most options are also blanked out when I right click in the window.
I'm thinking there is a simple fix to this, and I tried searching the forums to no avail. Sorry if this is a newbie question.
